Implementation Reference

• src/tools/site-settings.ts:176-195 (registration)

  Tool registration for ras_site_get_notifications with schema definition, title, description, annotations, and input schema configuration using server.registerTool
  server.registerTool( "ras_site_get_notifications", { title: "Notification Events", description: "Get notification event configuration, including alert triggers, email " + "notifications, and event thresholds. Use this to review which events " + "trigger admin notifications or verify alerting is properly configured.", annotations: READ_ONLY_ANNOTATIONS, inputSchema: {}, }, async () => { try { const data = await rasClient.get("/api/site-settings/notifications/events"); return { content: [{ type: "text" as const, text: JSON.stringify(data, null, 2) }] }; } catch (err) { return { content: [{ type: "text" as const, text: sanitiseError(err, "Failed to retrieve notification events") }], isError: true }; } } );
• src/tools/site-settings.ts:187-194 (handler)

  Handler function that executes the tool logic: makes a GET request to /api/site-settings/notifications/events API endpoint and returns formatted JSON data or sanitized error message
  async () => { try { const data = await rasClient.get("/api/site-settings/notifications/events"); return { content: [{ type: "text" as const, text: JSON.stringify(data, null, 2) }] }; } catch (err) { return { content: [{ type: "text" as const, text: sanitiseError(err, "Failed to retrieve notification events") }], isError: true }; } }
• src/tools/site-settings.ts:12-17 (schema)

  READ_ONLY_ANNOTATIONS constant providing metadata annotations for the tool (readOnlyHint, destructiveHint, idempotentHint, openWorldHint)
  const READ_ONLY_ANNOTATIONS = { readOnlyHint: true, destructiveHint: false, idempotentHint: true, openWorldHint: true, } as const;
• src/client.ts:128-166 (helper)

  RasClient.get method used by the handler to make authenticated GET requests to the RAS API with automatic token refresh and error handling
  async get(path: string): Promise<unknown> { // Ensure we have a valid session if (!this.authToken) { await this.login(); } const fetchOptions = { method: "GET" as const, headers: { ...this.headers, auth_token: this.authToken!, }, signal: AbortSignal.timeout(REQUEST_TIMEOUT_MS), }; let response = await fetch(`${this.baseUrl}${path}`, fetchOptions); // Token may have expired — re-authenticate once and retry if (response.status === 401) { await this.login(); response = await fetch(`${this.baseUrl}${path}`, { ...fetchOptions, headers: { ...this.headers, auth_token: this.authToken!, }, signal: AbortSignal.timeout(REQUEST_TIMEOUT_MS), }); } if (!response.ok) { const body = await response.text(); throw new Error( `RAS API error (HTTP ${response.status}) on ${path}: ${body.substring(0, 300)}` ); } return response.json(); }
• src/client.ts:43-54 (helper)

  sanitiseError function used to sanitize error messages by removing sensitive tokens/passwords and truncating long responses
  function sanitiseError(err: unknown, context: string): string { const raw = err instanceof Error ? err.message : String(err); // Remove anything that looks like a token or password value let sanitised = raw .replace(/auth_token[=:]\s*\S+/gi, "auth_token=[REDACTED]") .replace(/password[=:]\s*\S+/gi, "password=[REDACTED]"); // Truncate excessively long API response bodies if (sanitised.length > 500) { sanitised = sanitised.substring(0, 500) + "... (truncated)"; } return `${context}: ${sanitised}`; }
